I believe the wheels on your truck are hub centric. The worn holes are probably from loose lug nuts. Install the tires, Install the wheels, torque them and give them a good looking over everyone in a while!

Thanks, I was kind of thinking this also. This thing was probably a commercial gravel truck originally but became a farm truck many years ago. I worked for farmers as a kid and they overload these grain trucks bad. I think the overloading tends to make the lug nuts work loose and you end up with damaged holes. The tire guy thought they would be ok as long as I didn't drive it much. Thing is the cracked rim is no doubt worse, I have some other wheels I am going to have to look at as the one from my parts truck is in a little worse shape as far as the bolt holes. Think I have maybe 3 more out in my one building and have 2 on the front of the parts truck.
